Justin, Thank you very much for the explanation. Is the "Probe" another ICMP message? Does the "probe" have an ICMP Header? Does it mean that Source can include an "URL" to the ICMP message content? I reviewed the -08 version, I still can't find answers to my puzzle.

[JI] I think there might be a misunderstanding here. What we define for the in-band technique is just a simple way to include a probe description URI (a link, an email address, a phone number, etc) in probes/packets so that third parties on the path would be able to identify them (what's the reason for such probes? who's responsible for that? what's the purpose? etc). We do *not* define how third parties would verify the probe attribution (at least, we explain how, but we do not define a query to do that automatically). > Issues: > - Are those queries generated automatically? [JI] Not really sure about what you mean with "queries". See the above explanation. If I missed your point, please shout. > - If the queries are generated automatically, does it require routers > upgrade to support the auto-generating of those queries? - If the > queries are generated manually, the draft should give some detailed > examples since those queries will be generated by people not coming to > IETF. - Today, most routers ignore the Internet probes they don't support. What are the problems of ignoring them? [JI] No, routers do not need any upgrade. If the out-of-band technique, nothing is included in probes. If the in-band technique, the probe attribution is included in probes, but these bytes are just like data payload.
